I will get an error if I run the SAS code below.
Please give me some advise.
*ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required;

On a related note, if you do switch to %SYSEVALF, understand that the resulting &DIFF will contain a decimal point. That has the potential to cause problems down the road if &DIFF is used in later %EVAL functions.
